J’ai donc fait la migration de mon serveur ESXi 6.7 vers un serveur Proxmox 8.1.3. Je sais pas pourquoi je l’ai pas fait avant. Maintenant je peux faire des backups, des snapshots, …

J’ai eu aucun problème. Je conseille vivement le passage sous Proxmox qui me semble la meilleure alternative à VMWare. 
J’ai donc l’erreur :
